How many site-to-site VPN can PIX restricted License support?

Unanswered Question
Jan 14th, 2008

I have a PIX 515E with restricted license.

Current, I have about 5 users connecting PIX using Cisco VPN clients for Windows XP.

Recently, I plan to connect two branch offices to this PIX using site-to-site VPN. Each uses Cisco 877 ADSL router.

Here is my show version:

Cisco PIX Firewall Version 6.3(5)

Cisco PIX Device Manager Version 3.0(2)

This PIX has a Restricted (R) license.

If I connect these two remote routers to my restricted licensed PIX, do I need to use unrestricted license? If I don't, do I need to buy more memory?

Thanks

I have this problem too.

Hi

As your output shows there is no limitation in terms of numbers for IKE peers. The key thing as you point out is how much memory do you need. To which the answer is it really depends on how much traffic you are putting through the firewall, how much CPU it currently uses and how memory it is currently using.

If you have PDM there is a nice graphical output of the resource usage.
